Battery Selection Tutorial Course 1/3: Selecting your Cell and Cell Manufacturer(s)
After designing your product, you need to ensure the battery with which you are operating it will ensure the right performance and lifetime. When deciding this, narrowing down which chemistry (e.g. Li-ion, lithium primary, NiMH, etc.) best fits your product and which form factor are some of the first steps. Choosing a cell design (high-power vs. high-energy, for example) is another step and finally, finding the right cell manufacturer to fabricate your cells and packs. This webinar is the first in a three-part series on designing the right battery for your product. It will cover many of the key differences in chemistries, form factors, and cell designs and other best practices.
This webinar will focus on the following key topics:
• Choosing the right chemistry for your application
• Choosing the right form factor
• Choosing cell designs (e.g. high power vs. high-energy)

Preventing Li Ion Battery Failures From a Manufacturing and Design Perspective
How can you be proactive and make sure your cell supplier is the right one and you don’t end up with thermal events and field failures? Is it enough to qualify a cell manufacturer according to industry standards? The answer is that the majority of compliance based testing is related to abuse tolerance. However, the vast majority of field failures do not occur under abuse scenarios, but happen under normal operating conditions due to manufacturing flaws or design and system tolerance issues that cause internal shorts. In this webinar, you will learn about common lithium ion battery failure modes and how to be proactive in preventing these.
This webinar will focus on the following key topics:
• Gain an understanding of lithium ion battery failure mechanisms and the pathway to thermal events
• Learn how cell design impacts battery safety and reliability
• Learn the basic steps in a lithium ion cell manufacturing process, and how the process controls affect safety and reliability
• Come away with a checklist to qualify your cell manufacturer

Battery Selection Tutorial Course 3/3: Integrating Your Battery Into Your Product – Designing for Worst-Case Scenarios
The last part in Exponent’s three-part series, this webinar will focus on the finished product from the viewpoint of the battery. How can you best protect your battery within your device? Is your battery going to be user-replaceable? If you’re creating multi-cell packs, how should they be separated from (yet still connected to) each other? Should a thermal event occur, how can you prevent that from cascading through the whole pack? This webinar will help to answer many of those questions, and discuss design questions to help safeguard your battery pack throughout its entire lifecycle.
This webinar will focus on the following key topics:
• Creating multi-cell packs
• Containing thermal runaway events
